  2. US20180145800A1

    • Full Citation: US20180145800A1, [[Samsung Electronics Co.](/litigations/by-defendant/Samsung%20Electronics%20Co.), Ltd.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.), "Method of reducing power consumption in user equipment", Publication date: 2018-05-24, Priority date: 2016-11-24.
    • Brief Description: This patent application details a method for reducing power consumption in a user equipment.
    • Potential Anticipation (35 U.S.C. § 102): Similar to the previous citation, this reference addresses the broad concept of UE power saving, which is the underlying goal of US11368911. It might anticipate the general idea of reducing power consumption in a UE, but the specific mechanisms of using distinct search spaces and conditional monitoring for scheduling and power-saving signals, as defined in Claims 1 and 10, would need a detailed comparison.

  3. US20180270756A1

    • Full Citation: US20180270756A1, Qualcomm Incorporated, "Techniques and apparatuses for control channel monitoring using a wakeup signal", Publication date: 2018-09-20, Priority date: 2017-03-17.
    • Brief Description: This publication discloses techniques and apparatuses for control channel monitoring utilizing a wake-up signal (WUS). This directly relates to the WUS mechanism described in US11368911.
    • Potential Anticipation (35 U.S.C. § 102): This reference is highly relevant as it explicitly mentions "wake-up signal" and "control channel monitoring." It could potentially anticipate aspects of Claim 1 and Claim 10 concerning the use of a power-saving signal (WUS) and its association with a DRX functionality for wake-up information. The novelty of US11368911 may lie in the specific conditional non-monitoring of the WUS search space during DRX active time and the starting of the DRX on-duration timer based on not receiving the WUS.

  4. US20180332533A1

    • Full Citation: US20180332533A1, Qualcomm Incorporated, "Wake-up signal (wus) and wake-up receiver (wur) in a communication device", Publication date: 2018-11-15, Priority date: 2017-05-15.
    • Brief Description: This publication describes a wake-up signal (WUS) and a wake-up receiver (WUR) in a communication device.
    • Potential Anticipation (35 U.S.C. § 102): Similar to US20180270756A1, this reference's focus on WUS and WUR directly relates to the power-saving signal concept in US11368911. It may anticipate the general use of a WUS for power saving. However, the distinct configurations of two search spaces and the specific monitoring/non-monitoring behavior during DRX active time, as claimed in US11368911, would need careful comparison to determine full anticipation.

  5. US20190190582A1

    • Full Citation: US20190190582A1, Samsung Electronics Co., Ltd., "Method and apparatus for beam reporting in next generation wireless systems", Publication date: 2019-06-20, Priority date: 2017-12-19.
    • Brief Description: This patent application describes methods and apparatus for beam reporting in next-generation wireless systems. While related to wireless communication, its primary focus is beam management rather than specific PDCCH monitoring for power saving using WUS.
    • Potential Anticipation (35 U.S.C. § 102): This reference is less directly related to the core innovation of US11368911. It is unlikely to anticipate Claims 1 or 10, as its subject matter (beam reporting) does not appear to cover the specific aspects of power-saving PDCCH monitoring using distinct search spaces and conditional monitoring behavior.

  6. US20190254110A1

    • Full Citation: US20190254110A1, Samsung Electronics Co., Ltd., "Method and apparatus for power savings at a user equipment", Publication date: 2019-08-15, Priority date: 2018-02-14.
    • Brief Description: This publication outlines a method and apparatus for power savings at a user equipment.
    • Potential Anticipation (35 U.S.C. § 102): This reference broadly covers power-saving methods for UEs. It potentially anticipates the overarching goal of power saving in Claims 1 and 10. The extent of anticipation would depend on whether its disclosed power-saving techniques involve the specific combination of search space configurations, WUS monitoring, and conditional non-monitoring during DRX active time as claimed in US11368911.

  7. US20190297577A1

    • Full Citation: US20190297577A1, Samsung Electronics Co., Ltd., "Method and apparatus for power saving signal design in nr", Publication date: 2019-09-26, Priority date: 2018-03-23.
    • Brief Description: This publication focuses on the design of power-saving signals in New Radio (NR) systems.
    • Potential Anticipation (35 U.S.C. § 102): This is another highly relevant reference as it discusses "power saving signal design in NR," which directly relates to the "power saving signal" (WUS) in US11368911. It could potentially anticipate aspects of the second configuration and the use of a power-saving signal as described in Claims 1 and 10. A detailed comparison would be needed to see if the specific monitoring behaviors and interactions with DRX active time, as claimed in US11368911, are also explicitly or inherently present.

  8. US20200037396A1

    • Full Citation: US20200037396A1, Toufiqul Islam, "Downlink control channel signaling for improving ue power consumption", Publication date: 2020-01-30, Priority date: 2018-07-24.
    • Brief Description: This publication describes downlink control channel signaling aimed at improving UE power consumption.
    • Potential Anticipation (35 U.S.C. § 102): This reference addresses improving UE power consumption through downlink control channel signaling, which aligns with the general problem US11368911 seeks to solve. It might anticipate aspects of the power-saving methodology, but the specific configuration of two distinct search spaces and the conditional monitoring logic for WUS during DRX active time would need to be compared to determine anticipation of Claims 1 and 10.

  9. US20200092814A1

    • Full Citation: US20200092814A1, Hua Zhou, "Power Saving in a Wireless Communication System", Publication date: 2020-03-19, Priority date: 2018-09-19.
    • Brief Description: This publication focuses on power saving in a wireless communication system.
    • Potential Anticipation (35 U.S.C. § 102): This broadly covers power-saving techniques in wireless communication. Like other general power-saving references, it could anticipate the overall goal, but the specific implementation details of US11368911, particularly the dual search space configuration and the conditional non-monitoring of the power-saving signal during DRX active time, would likely remain novel unless explicitly detailed in this reference.

  10. US20200229092A1

    • Full Citation: US20200229092A1, Samsung Electronics Co., Ltd., "Method and apparatus for monitoring physical downlink control channel", Publication date: 2020-07-16, Priority date: 2019-01-10.

    • Potential Anticipation (35 U.S.C. § 102): This reference is very relevant as it deals with "monitoring physical downlink control channel," which is the core subject of US11368911. It is likely to anticipate aspects of how PDCCH monitoring is performed. The key for US11368911's novelty would be the specific two-search-space approach, the power-saving signal, and the conditional non-monitoring during DRX active time, which would need to be thoroughly compared against this reference.

  11. US20210022202A1

    • Full Citation: US20210022202A1, Samsung Electronics Co., Ltd., "Method and apparatus for performing discontinuous reception in wireless communication system", Publication date: 2021-01-21, Priority date: 2018-03-29.
    • Brief Description: This publication describes methods and apparatus for performing discontinuous reception (DRX) in a wireless communication system.
    • Potential Anticipation (35 U.S.C. § 102): This reference is highly relevant due to its focus on "discontinuous reception (DRX)." Since US11368911's claims are explicitly tied to DRX functionality and DRX active time, this prior art could potentially anticipate various elements related to DRX operation. The specific novelty of US11368911 would rest on the combination of a power-saving signal, distinct search spaces, and the precise rule of not monitoring the power-saving signal search space during DRX active time, and how this differs from or builds upon the DRX methods in this reference.
